Comparative effectiveness of different probiotics combined with phototherapy for neonatal hyperbilirubinemia: a retrospective, non-randomized cohort study.
Article in Frontiers in pediatrics, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Objective: This is a retrospective cohort study, not a clinical trial. No randomization, allocation concealment, or trial registration was performed. Phototherapy serves as the standard treatment for neonatal hyperbilirubinemia, yet clinical issues such as bilirubin rebound and prolonged hospital stay remain unresolved. This study compares the clinical efficacy and safety of two different probiotic regimens as adjuvant therapy to phototherapy. Methods: A retrospective analysis was conducted on 377 infants diagnosed with neonatal hyperbilirubinemia who were hospitalized in the Department of Neonatology, The Fifth Affiliated Hospital of Guangzhou Medical University between January 2021 and December 2023. Patients were divided into three groups according to the actual treatment received (phototherapy alone, phototherapy + Bifidobacterium quadruple viable tablets, or phototherapy + Bacillus subtilis and Enterococcus faecium viable granules). No randomization or blinding was applied due to the retrospective design. No trial registration was performed. Outcome measures included the dynamic trend of transcutaneous bilirubin, duration of phototherapy, length of hospital stay, total medical cost, and incidence of adverse reactions. Results: Both probiotic groups had shorter stays and fewer adverse reactions than phototherapy alone. After multivariable adjustment, Group B vs. A: hospital stay -0.52 days (95% CI: 0.24-0.80; Conclusions: Phototherapy combined with probiotics, particularly *Bacillus subtilis* and Enterococcus faecium viable granules, was associated with faster and sustained bilirubin reduction, helps prevent bilirubin rebound in the mid-treatment stage and shortens hospital stay, which may represent a potentially beneficial strategy for neonatal hyperbilirubinemia.
